bent forwardly parallel to the portion 14', and from thence the nietal is looped upward at 144, linally passing downward at 14, Where an eye 14. is provided. In practice the eye is made by bending the metal circularly around, so as to leave a central opening, and the material is Vlinally bent upward at 147. Arranged to embrace and held in position by the pole-faces 142 is a slieet-metal clip 15 of non-magnetic metal, which prevents the pole-faces lei from contacting with the electromagnet 12. 16 indicates a second sheetnietal clip, which should be made of spriiigy copper and which is organized into the armature by being bent under the portion 147 thereof. It will be seen that the entire armature is composed of but three pieces and that all of them may be arranged and 'formed and finally organized together in an ordinary die-press.

17 indicates a stud which is inset into a hole 18 in the base-plate 1, an insulating- Washer 19 being introduced to insulate vthe stud from the base.

20 indicates a pin which connects the ears or lugs 7, previously described, and forms a pivot bearing or support for the armature 13.

lVhen the parts are organized, the spring' blade 16, which has a platinum or non-corrosive surface 16 thereonl1es in close proximity to the metallic stud 17 and is adapted'v to make and break a sliglitly-sliding contact therewith when the armature is-vibrated.

21 indicates a pin attached to the casing 1, which constitutes a support for the spiral spring 2 2, connected to an eye 23,'provided in t ie armature for this purpose.

24 indicates the usual diaphragm, which may be of the usual ferrotype metal of any convenient or approved construction, which forms no part of our invention. The electrical circuits are generally indicated in Fig. 2, in which 1 indicates a lead-Wire which is grounded on the base 4. From this base the current enters the armature 13 and normally finds a path through the spring-blade 16 into the stud 17.

1L indicates a Wire which leads from the .stud 17 to the electromagnet 12, and 13 indicates second wire or connection which coinplctes the circuit to the return-lead 1.

In operation the circuit is completed in the manner above described, and` the magnet 12 i e ergi/ d. ri`he energization of the mag its both the diaphragm 24 and 13 through the Wedge-shaped Tlv.' traction of the arma- 'the i ircuit at 16 in the usual a i we for the ear-ineinch is boned( al' to deaf persons.

. anintermediate V-shaped 1. In an ear-massage apparatus, a magnet, an armature formed of a singlev piece of iron bent or doubled upon itself and having a circuit-niaking clip engaged between adjacent portions so as to be held thereby.

2. In an ear-massage apparatus, a magnet, a T-shaped armature therefor having a pair of armature-faces and a wedge-shaped portion projecting therebetween, and a spring metal clip secured to said armature and forming a circuit breaker or interrupter therefor.

3. In an earmassage apparatus, a diaphragm, a magnet comprislngy a base-plate and projecting studs having coils, anarmature comprising a piece of'sheet iron-bent so as to forni armature-faces with an intermediate V-shaped portion therebetween, said armature being also bent to form an eye constituting. a pivot-bearing, and a circuit breaker or interrupter attached to saidarmature.

1. In an ear-massage apparatus, abaseplate having projecting iron studs thereon, coils surrounding said studs to form an electromagnet, an armature ivoted to said baseplate and having apairo armature-faces and ortion projecting between the oles of said electroinagnet, and a circuit brea er or interrupter on said armature. y

5. 1n an ear-massage apparatus, a baselplate having a pair of projecting iron cores thereon, coils surrounding said cores, an l armature comprising a single piece of sheet metal pivoted to said base-plate and bent to form a pair of armature-faces having an intermediate projecting V-shaped portion, and an interrupter secured to said armature.

6. In an ear-massage apparatus, ,a baseplate `having a pair of ears or lugs thereon, an electrical connection grounded on one of,s a1d lugs, and a second electrical connection 'hushed into the other lug, an electromagnet supported by said ybase-plate, a vibrating armature supported by said .base-plate, an

"insulated stud pro]ecting into proximity to said armature, and electrical lead-Wires connecting said electromagnet to said 4stud and said hushed connection. v

7. In an ear-massage apparatus, ay basevplate having a pair of lugs thereon forming supports for a pair of electric terminals, a second pair of lugs arrangedto constitute pivot-liearings, a vibratory armature sup# ported by the said pivot-bearings and an electroniagnet supported by saidbase.

In u itness whereof We subscribe our signa tures in the presence of two witnesses.
